category-opportunity-index

Reports the JoomPulse opportunity index (low, medium, or high) for one Mercado Livre (Brasil) category, alongside that category's current monthly market stats — estimated GMV, estimated sales, number of active sellers, number of active listings, and average ticket — then writes a plain-language read on how attractive the category is to enter. Use it when a seller wants a one-shot market snapshot for a category they name. Triggers include: "is this category worth entering", "show the opportunity index for this category", "how big is this market", and the pt-BR equivalents "qual o índice de oportunidade", "vale a pena entrar nessa categoria", "tamanho de mercado da categoria". Sales and revenue are JoomPulse estimates, not real transactions. For ranking the sellers in a category, use the top-sellers-in-category skill; for trending search terms, use the top-keywords-in-my-category skill; for comparing category aggregates against a user-supplied previous snapshot, use the category-monitor skill.
